Abstract (en)

[origin: WO2020109557A1] The invention relates to a keyless coupling for a tool shaft (1) and a handpiece (2) of a surgical instrument (4) having a first coupling section (6), which is provided on a proximal section of the tool shaft (1), a second coupling section (8), which is provided on a distal section of a shaft holder (10) of the handpiece (2), and a locking/unlocking element (12). The locking/unlocking element (12) is arranged on the tool shaft (1) and forms a latching section (14), and the shaft holder (10) has at least one undercut, more particularly a recess (16), which is provided and adapted for receiving the latching section (14) in a locking position of the two coupling sections (6, 8) such that the latching section (14) and the undercut, more particularly recess (16), are in latching engagement with one another and secure the two coupling sections (6, 8) against a relative axial movement with respect to one another at least in the pulling direction.
